Contact lens with optical prophylaxis

ABSTRACT

The present disclosure provides metalloporphyrin and metallochlorin compounds (e.g., compounds of Formula (II) and (III)), which are useful in the preparation of optical devices (e.g., contact lenses, intraocular lenses, implantable contact lenses) that protect retinal pigment epithelium by the selective blocking of blue light. Also provided are precursor porphyrin and chlorin compounds (e.g., compounds of Formula (I)), and compositions and optical devices incorporating the compounds of the disclosure. Also provided are methods of selecting appropriate metalloporphyrin and metallochlorin compounds for incorporation into optical devices wherein the devices mitigate damage to retinal epithelial cells while balancing changes to luminous transmission, discomfort glare, color distortion, and disruption of circadian rhythms.

RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application 63/275,159 filed Nov. 3, 2021, the entirety of which is incorporated herein by reference.

BACKGROUND

There exists a need for protecting the eye from damage by the most energetic photons in the blue and violet regions of the electromagnetic spectrum. Shehade et al. disclosed in U.S. Pat. No. 8,833,937 a retinal light management system that targets compromised patients by blocking light with wavelengths between 451 and 600 nanometers (nm). However, this approach does not account for substantial reduction in luminous transmission, interference with circadian rhythms, or color distortion.

Ishak disclosed, in U.S. Pat. No. 8,403,478, an ophthalmic lens with a reflective rugate filter that blocks visible blue light with wavelengths between 400 and 475 nm. This disclosure also did not account for interference with circadian rhythms, and the transmission profile of a rugate filter varies with both angle of incidence and polarization. The same inventor acknowledged color distortion and melatonin suppression by dye-loaded lenses in U.S. Pat. No. 10,610,472 obliquely but did not describe how to achieve retinal protection subject to these constraints.

Blue blocking has also been proposed for contact lenses. Newman et al. disclosed in US Application 2021/0132416 a contact lens that blocks at least some light between 400 and 500 nm. However, Newman fails to address luminous transmission, color distortion, or circadian rhythm interference. Moreover, the question of biocompatibility is not considered since, in paragraph [175] of the application “ . . . any appropriate type of blocking agent may be used to block UV or blue light wavelengths.”

Another approach to blue blocking contact lenses is described in U.S. Pat. No. 7,364,291, where alternate concentric circular rings of photochromic dyes are incorporated to block UV or blue light. As in Newman, broad wavelengths from 100 to 515 nm are described as being partially blocked but considerations of inevitable circadian, color distortion, or luminous transmission effects are not disclosed.

Yet another contact lens with blue blocking characteristics is disclosed by J. Y. Park in EP 3424688. This soft contact lens is manufactured with the dye 4-[(E)-phenyldiazenyl]phenyl-2-methacrylate or a like composition with substantial absorptivity above 500 nm, so it will interfere with circadian phase locking, color perception, and both scotopic and photopic luminous transmission.

A final example of blue-blocking lens disclosures is found by Y. C. Lai et al. in U.S. Pat. No. 7,276,544. They describe a process for manufacture of intraocular lenses with blue light absorption characteristics but as with Park's application there is no consideration of melatonin suppression, color distortion or luminous transmission attenuation.

Accordingly, there is a need for blue light-blocking lenses that come into intimate contact with the eye, either at the corneal surface as a contact lens or in the vitreous humor as an intraocular lens, that simultaneously minimize interference with circadian rhythms, luminous transmission during day and at night, and perceived colors.

SUMMARY

The present disclosure provides compounds, compositions, devices, and methods that protect optical device wearers from damage to retinal pigment epithelium. This protection is balanced by the unavoidable effects of reducing internal transmission of the device at toxic wavelengths on color distortion, circadian rhythm phase locking by melatonin suppression, luminous transmission, and discomfort glare.

Various conditions for effecting polymerization (e.g., free radical polymerization) are known in the art. Polymerization can be effected, for example, actinically (i.e., by use of an irradiation with UV or a visible light), or thermally (i.e., by heating) in the presence of a free-radical initiator.

The term “transition metal” refers to elements that are in the d-block and f-block of the Periodic Chart of the Elements, which may exhibit a variety of oxidation states, and which may form numerous complex ions. The term “d-block” refers to those elements that have electrons filling the 3d, 4d, 5d, and 6d orbitals, and the term “f-block” refers to those elements (including lanthanides and the actinides) that have electrons filling the 4f and 5f orbitals. Exemplary transition metals include palladium, nickel, cobalt, copper, platinum, silver, manganese, zinc, iridium, rhodium, iron, and ruthenium. The term “transition metal” also includes alloys, metal/metal composites, metal ceramic composites, and metal polymer composites, as well as other metal composites.

As used herein, the term “salt” refers to any and all salts. Salts include ionic compounds that result from the neutralization reaction of an acid and a base. A salt is composed of one or more cations (positively charged ions) and one or more anions (negative ions) so that the salt is electrically neutral (without a net charge). Salts of the compounds of this invention include those derived from inorganic and organic acids and bases. Examples of acid addition salts are salts of an amino group formed with inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or with organic acids, such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, hippurate, and the like.

Further salts include ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.

The term “tautomers” or “tautomeric” refers to two or more interconvertible compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa). The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Tautomerizations (i.e., the reaction providing a tautomeric pair) may catalyzed by acid or base. Exemplary tautomerizations include keto-to-enol, amide-to-imide, lactam-to-lactim, enamine-to-imine, and enamine-to-(a different enamine) tautomerizations.

It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”.

Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn, Ingold, Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In case of conflict, the present document, including definitions, will control. Preferred methods and materials are described below, although methods and materials similar or equivalent to those described herein can be used in practice or testing of embodiments of the present disclosure. The materials, methods, and examples disclosed herein are illustrative only and not intended to be limiting.

The term “about X,” where X is a number or percentage, refers to a number or percentage that is between 99.5% and 100.5%, between 99% and 101%, between 98% and 102%, between 97% and 103%, between 96% and 104%, between 95% and 105%, between 92% and 108%, or between 90% and 110%, inclusive, of X.

The terms “first,” “second,” “third,” and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

Use of the phrase “at least one instance” refers to 1, 2, 3, 4, or more instances, but also encompasses a range, e.g., for example, from 1 to 4, from 1 to 3, from 1 to 2, from 2 to 4, from 2 to 3, or from 3 to 4 instances, inclusive.

Compound and Device Design

The present disclosure describes methods, compounds, and lens devices that mitigate damage to retinal epithelial cells while balancing changes to luminous transmission, discomfort glare, color distortion, and disruption of circadian rhythms and that simultaneously comply with constraints based on chemical stability during manufacture, photobleaching or oxidation, and contact with living tissues.

Optical Transmission

The energy of photons absorbed by retinal pigments is inversely proportional to their wavelength. The primary mechanism of retinal damage by blue and violet light is known to involve absorption by pigments such as lipofuscin that trigger production of reactive oxygen species. Careful measurements of these processes have resulted in action spectra for the impact of different wavelengths of light on damage to retinal pigment epithelial (RPE) cells, as described for example in Marie et al. Cell Death and Disease (2018) 9:287 or Hammond et al. in Clinical Ophthalmology 2019:13 2427-2438, and shown in FIG. 1 . The contribution to retinal damage for incident light with a given spectrum is quantified by integrating the product of the action spectrum times the incident spectrum over visible wavelengths from 380 to 800 nm.

The sensitivity of the human visual system is also characterized by wavelength dependencies that vary with the overall scene luminance. The sensitivity functions for night (scotopic) visual acuity are shifted to the blue compared with those for daylight (photopic) vision as shown in FIG. 1 . Intermediate (mesopic) luminance visual acuity is intermediate between these sensitivity spectra and is not shown because of its complex dependence on other contextual factors.

Discomfort glare is also disproportionately perceived by light of shorter visible wavelengths, as shown in FIG. 1 and described in detail in U.S. Pat. Nos. 10,545,264 and 10,935,709 and Fekete et al. Ophthal. Physiol. Opt. 2006 26: 313-317. The spectral variation of discomfort glare is also reproduced in FIG. 1 .

Another factor that requires consideration when filtering visible light is the mechanism by which blue light suppresses melatonin synthesis. The fading of blue light provides a phase locking signal for circadian rhythms with explicit wavelength variation defined in the action spectrum reported by Brainard et al. in The Journal of Neuroscience, 21(16), 6405-12, 15 Aug. 2001.

Internal absorption is also known to influence the perceived color of objects, so consideration of this effect, though slightly more complex, is also important. Color distortion is most conveniently calculated using the L*a*b* uniform color space in which framework one unit of length corresponds to a ‘just noticeable difference’ in color based on psychophysical measurements with human observers and controlled illumination. The full range of colors visible to humans is spanned by the 1269 Munsell color tiles as described, for example, by Romney and Indow, Color research and application, 28(3), 182-96, 2003. The color shift in uniform color space can be calculated based on the displacement in L*a*b* for each of the color tiles when internal absorption by dye is incorporated. This approach is amply described in the prior art, for example in U.S. Pat. No. 9,063,349. Incorporating the shift in color space can be accomplished by using a statistical moment of the distribution of L*a*b* shifts such as the mean, median, or variance, or a simple sum of all of the displacements, as illustrated in the embodiments below.

Chemical Stability Factors

Manufacturing processes for contact and intraocular lenses require varied chemical conditions. First, internal transmission is limited by the range of products of lens thickness, dye concentration, and extinction coefficient that can be achieved with the required solvents and resins.

Second, the dye must be chemically stable under the reaction conditions required for their manufacture. These include interaction with reactive species present during thermal or photochemical polymerization, elevated pressures and temperatures encountered in injection molding, and exposure to oxygen.

Third, the final product must be biocompatible; the dye material is preferably neither toxic nor irritating and is incorporated into the product by covalent bonds.

Finally, the dye incorporated into the lens matrix must be photostable. Contact lenses, which are exposed to ambient light, air, and fluid on the corneal surface, must resist photooxidative degradation for the duration of its use. Intraocular lenses similarly must withstand light that penetrates the iris and remain compatible with the vitreous humor, in this case for a much longer time than for a contact lens.

Chemical Families: Porphyrins and Chlorins

The following embodiments describe the method of the disclosure for compositions with porphyrin or chlorin ring configurations, representative examples of which are shown in FIGS. 2 and 3 .

The term “porphyrin” refers to a group of heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their a carbon atoms via methine bridges (═CH—). With a total of 26 π-electrons, of which 18 π-electrons form a planar, continuous cycle, the porphyrin ring structure is often described as aromatic.

The term “chlorin” refers to a group of compounds related to the porphyrins. Chlorins are reduced derivatives of porphyrins (i.e., dihydroporphyrin) wherein one pyrrole has been converted to a pyrroline.

These materials have planar, conjugated p-orbitals on a rigid ring that may also include a metal with d-orbitals that interact with the pi cloud of the heteroatomic ring system. These features provide the basis for strong optical absorption in the blue and violet spectral regions. However, other dye materials with the requisite extinction coefficient, solubility, and chemical stability may also be employed according to this method.

Design Embodiments

The absorption spectra for the porphyrin and chlorin dyes are shown in FIGS. 4 and 5 . According to the present disclosure these spectra must be translated to transmission spectra based on the product of available concentration and path length for the lens. An example of this transformation for a (concentration*path-length) product 3×10⁻⁶ liters/mole is shown for each of the porphyrin dyes in FIG. 6A-C. Each porphyrin transmission spectrum has different detailed shapes in the 400-450 nm region and has different internal transmission values in the 500-700 nm region where color distortion and luminous transmission are affected.

The relative impact of internal absorption by these dyes is computed by integrating the product of the action spectra with a dyed lens and dividing by the integral of the action spectra with no dye. The resulting percentages are show for the 13 porphyrin dyes and each of the optical qualities, photopic and scotopic luminous transmission, retinal pigment epithelial toxicity, melatonin suppression, and discomfort glare in FIG. 7 .

The average color distortion and its standard deviation using the above calculations for these 13 dyes at a concentration*path-length product of 3×10⁻⁶ l/mol are shown in FIG. 7 .

The next and final step in ranking the optical performance of each dye combines the transmissive property changes with the color distortion using a weighting function that quantifies the relative importance of each property displayed in FIG. 8 . Table 1 displays the impact to these properties based on changes to the integrals of the various action spectra for each of the 13 porphyrin dyes displayed in Figure at c*l=3×10⁻⁶ l/mol and the average color distortion.

The simplest weighting function for ranking these dyes is a vector whose elements are +1 for desirable properties and −1 for undesirable properties: [1 1 −1 1 −1 −1]. The inner product of each column corresponding to a different dye is shown in FIG. 8 . Under this weighting scheme at concentration*path-length products of 3×10⁻⁶ dyes 1, 4, and 11 have the highest merit while dye 13 is least attractive. If market or other factors drive the relative prominence of each component this is easily incorporated in the weighting function. Referring to FIG. 8 the performance of the same 13 dyes is displayed (-o-) when the weighting function is [0.0976 0.0976-9.76-0.0976 0.0976], implying that the protection of RPE is ten times as important as each of the other factors. As displayed, this change has a large impact on the suitability of dye 13, which goes from least to most suitable when RPE protection is most heavily weighted.

In another embodiment, the concentration of a dye can be adjusted to useful concentrations by evaluating the weighted properties for transmission spectra calculated at different concentrations, subject to solubility and chemical stability constraints, at a prescribed lens thickness. The absorption and transmission spectra at increasing c*l products for the copper chlorin CuC-1 are displayed in FIG. 9 . Referring to FIG. 10 , the influence of increasing concentration for each of the optical properties is displayed for c*l ranging from 0 to 2×10⁻⁵ mol-cm/l. Incorporating the color shift and uniform weighting as described for comparison among porphyrins results in a local maximum for the weighted properties of between 2 and 4×10⁻⁶ as shown in FIG. 11 . Enhancing the weight of RPE protection by a factor of ten over the remaining properties changes this picture, with slowly increasing weighted properties c*l above 10⁻⁵.

A further embodiment of the disclosure entails simultaneous maximization of the weighted properties with respect to both dye composition and concentration.

Yet another embodiment of the disclosure uses transmission spectra computed from mixed compositions involving two or more chemically compatible dyes where the ratio of individual dyes is also adjusted to maximize the weighted properties.

Thus, in one embodiment, disclosed is a method of designing an optical device that protects retinal pigment epithelium from blue light, the method comprising:

providing a first optical device comprising a porphyrin or chlorin compound;

providing a second optical device that is identical to the first device without the porphyrin or chlorin compound;

dividing the integral obtained for the first device by the integral obtained for the second device for that measured property to provide a change in the transmissive property;

measuring a color shift in uniform color space for the first optical device as compared to the second optical device;

combining the transmissive property changes and the color shift using a weighting function that quantifies the relative importance of each property; and

ranking optical performance of the porphyrin or chlorin compound.

In certain embodiments, the method includes measuring at least three of photopic luminous transmission, scotopic luminous transmission, retinal pigment epithelial toxicity, melatonin suppression, and discomfort glare for each of the first and second optical devices.

In certain embodiments, the method includes measuring at least four of photopic luminous transmission, scotopic luminous transmission, retinal pigment epithelial toxicity, melatonin suppression, and discomfort glare for each of the first and second optical devices.
